Full Tensor Gravity Gradiometry (FTG) is a core service at Metatek. FTG Meaning – Full Tensor Gravity Gradiometry is a way of measuring changes in the density of the subsurface caused by subsurface geology. It is used by natural resource and mineral prospectors to measure and map changes ...
3D Full Tensor Gradiometry (FTG) or high-precision moving platform gravity gradiometry measures the full gravity field in all directions. The technology was initially commercialised for the petroleum exploration industry to assist with defining complex salt structure/geometry, sub-salt play definition an...
In airborne gravity gradiometry, the Gravity Module Assembly is an optional gravimeter unit that is mounted on the same stabilized platform as the Full Tensor Gradiometer. Direct measurements of the gravity field are needed from this device to constrain the long wavelengths when gradient data are ...
FTG Gravity data acquired on airborne and marine platforms measure 5 independent Tensor components that describe a total gravity field. The components capture unique signature patterns related to attributes of target geology that when collectively interpreted enable detailed imagery of the target itself in...
Quantum sensing stands for all quantum technologies that measure various physical variables such as external magnetic or electric fields, gravity gradient, acceleration and rotation. Quantum sensors can produce very precise information about an electric signal, magnetic anomalies and for inertial navigation....
In 2021-2022 North Central Gold acquired more than 18, line-km airborne gravity gradiometry (AGG), scalar vertical gravity, and total magnetic field intensity (TMI) data over tenements in the Stawell Corridor north of Horsham in north-western Victoria. The purpose of the survey was to improve...
of both constants to gravity. Atomic clock networks can also be used to place bounds on Topological Dark Matter (TDM) models. TDM can be expressed as a scalar field that couples to fundamental constants such as the fine-structure constant and the electron mass, thus producing variations in ...

We present a denoising method based on the translation-invariant wavelet with mixed ...
However, full-tensor gradiometry (FTG) data are contaminated by high-frequency random noise. The separation of noise from high-frequency signals is one of the most challenging tasks in processing of gravity gradient tensor data. We first derive the Cartesian equations of gravity gradient tensors ...
Interpreting full tensor gravity gradiometry data (FTG) depends on clear delineation of signature patterns arising from sub-surface geology. However, challenges presented by depth uncertainty and the presence of a noisy anomalous overprint characterized by a high frequency, low amplitude anomaly field ...
